Definitions

  • the present invention relates to a method for the adaptation or adjustment of a machine support where the weight of a machine is accommodated exclusively by a main support.
  • FIG. 1 shows a machine support having a main support
  • FIG. 2 shows a machine support having a main support and an auxiliary module that is connected in parallel thereto.
  • At least one auxiliary module which is relieved or free of the weight of the machine, is connected in parallel to the main support in such a way that as a consequence of the spring rigidity of the auxiliary module, the spring system combination of the main support and of the auxiliary module corresponds to prescribed characteristics of dampening and inherent frequency.
  • the main support is designed only for accommodating the weights, one can freely select the spring rigidity of the auxiliary module in such a way that desired characteristics with regard to dampening and inherent frequency are achieved.
  • Spring characteristics of the auxiliary module can be adapted or adjusted not only in one direction, for example the vertical, but also in the two directions that are at right angles thereto.
  • FIG. 1 shows a machine 1 that is supported on a machine foundation or bedplate 3 via a machine support.
  • the machine support here in the function of a main bearing or support 2 , is formed from a spring 4 having a rigidity C 1Z .
  • the coordinate system is established by the orthogonal coordinates x, y, z.
  • the z coordinate is the vertical direction in which the weight of the machine 1 acts.
  • the rigidity C 1Z of the spring 4 is adapted to the weight and is relatively soft.
  • inventively connected in parallel with the spring 4 of the main support 2 is at least one auxiliary module 5 in the form of a second spring 6 .
  • this second spring 6 is relieved of any weight of the machine 1 , i.e. the second spring 6 is installed only after the inward deflection of the spring 4 into the intermediate space that remains between the machine 1 and the machine bedplate 3 .
  • the rigidity C 2Z of the second spring 6 can be provided merely on the basis of desired inherent frequency of the oscillating system that is formed from the mass m of the machine 1 and the rigidities C 1Z +C 2Z .
  • the inherent frequency can be varied by the selection of the rigidity C 2Z such that damaging resonance is avoided.
  • auxiliary module 5 can also be formed by a plurality of springs, for example by including a third spring 7 having a rigidity C 3Z , with this spring being connected in parallel with the main support 2 .
  • the use of the inventive auxiliary module 5 also allows influencing of rigidity in the x and y directions.
  • the indices x, y, z indicate the direction of the rigidity.
  • the inventive method makes it possible to adapt the machine support of an already installed machine or engine, without having to remove the machine. This is particularly advantageous with internal combustion engines that serve for driving a boat or similar vessel. Since in such situations very small installation conditions exist, the inventive method is assembly friendly, especially since it is not necessary to undertake any readjustment of the system.
